"That television disappears."
Translation:그 텔레비전은 사라져요.
져 is the conjugated end of the verb 사라지다: to disappear. 요 is just a polite ending.
For many verbs, adding 져 to the end means to become whatever the verb is. For example 예뻐요 means pretty. 예뻐져요 means to become pretty. That soumds weird but you can say. 그 여자는 예뻐졌어요 meaning "That woman became pretty"
~지다 added to a verb adds the meaning "becomes" (좋지다 = to become good, 달라지다 = to become different/change), however I'm pretty sure 사라지다 hasn't a more basic root form so I suppose it's just a normal conjugation in the 요 form.
